Poppler is a fork of the xpdf PDF viewer developed by Derek Noonburgof Glyph and Cog, LLC. The purpose of forking xpdf is twofold.First, we want to provide PDF rendering functionality as a sharedlibrary, to centralize the maintenence effort. Today a number ofapplications incorporate the xpdf code base, and whenever a securityissue is discovered, all these applications exchange patches and putout new releases. In turn, all distributions must package and releasenew version of these xpdf based viewers. It's safe to say thatthere's a lot of duplicated effort with the current situaion. Even ifpoppler in the short term introduces yet another xpdf derived codebase to the world, we hope that over time these applications willadopt poppler. After all, we only need one application to use popplerto break even.
